On Sept. 15, 2016, China launched its uncrewed Tiangong-2 space lab to Earth orbit. Learn all about the spacecraft, which China views as a key step toward building a bona fide space station, in this infographic.
The China Manned Space Engineering Office published a brief description of Tiangong-2 and its successor Tiangong-3 in 2008, indicating that at least two crewed spaceships would be launched to dock with Tiangong-2.
Tiangong-2 was originally expected to be launched by the China National Space Agency by 2015 to replace the prototype module Tiangong-1, which was launched in September 2011. In March 2011, Chinese officials stated that Tiangong-2 was scheduled to be launched by 2015, following the deorbit of Tiangong-1. An uncrewed cargo spacecraft will dock with the station, allowing for resupply.
